Effects of the atmosphere on a balloon?

Question

A helium-filled balloon is let out into the atmosphere. It is made out of a "super" material that will allow it to compress and expand indefinitely - without leaking or exploding. Will the balloon expand/compress? What will happen to the balloon as it rises? At what point, if any,will stop?

Answer 1

The higher up it goes the colder it gets thus the helium atoms slow down and fail to maintain the balloons shape which will probably eventually cause the balloon to lose altitude at a certain point. My guess is that assuming this super material doesn't allow any of the helium to escape, and ingnoring the changing seasons and regions, is that it will eventually find an equilibrium in the atmosphere in which it will float indefinitely, rising and falling. If this balloon somehow managed to make it out to space the balloon would become amorphous and could possible expand indefinitely.

Hot = Excited atoms/molecules = expand
Cold = Lethargic atoms/molecules = contract

Low pressure will make the balloon expand like the other girl mentioned so I guess you would have to make a comparisson of pressure vs. temperature. It's really kind of a complex question.

Answer 2

Well, volume of gas increases as pressure decreases. Pressure (air pressure) decreases when you go to high altitudes. So, most likely, the balloon will expand as it rises. I don't think that it will stop since the balloon is made from a super material that will let it compress or expand indefinitely. It will just continue to expand, without stopping.

(But that's just impossible. I mean, a super material. Heehee. :P)

Answer 4

it will expand indefinitely, if it reaches outer space(vacuum), the pressure inside will cause it to expand... a lot
